SPECFCATION forming part of Letters Patent No. 420,658, dated February4, 1890. Application filed August 26, 1889. Serial No. 321,980. (Nomodel.)

To all whom, t may concern:

Be it known that I, GEORGE HAYES, a resident of the city, county, andState of New York, have invented a new and useful Metallic Lathing, ofwhich the following is a speci- Iication.

My invention consists of a lathing of sheet metal having at intervalsthroughout oblong apertures, each aperture having two tongues or hooksof the metal turned outward in forniing the apertures, one tongue ateach end of the oblong aperture and projecting beyond the plane of thesheet, and with a bend backward from the aperture, so that they willbecome embedded in the mortar when applied thereto, and serve to Securethe saine to the line w 0c of Fig. l, as applied vertically. Fig.'

3 is a section of the lath as applied to a ceiling. Fig. 4 is aperspective view of a piece of the lath with one opening.

On the drawings, A indicates the sheetlnetal lath,B the apertures, and Cthe turnedout metalforming the hooks or barbs. In forming the same I outthe metal, as shown y in the upper left-hand corner of Fig. l, with twolong parallel slits d and a', united at a point intermediate of theirlength bya crossslit b,for1ning an H. Then Iforce outwardly the metalbounded by the cuts and backwardly to each end to form the hooks.

Plaster when applied to the surface of the lath beds itselt` around thehooks.

NVhat I claim as new, and desire to secure by Letters Patent of theUnited States, is-

l. A lath of sheet metal having at intervals throughout aperturesof'oblong shape, each having at its two short sides or ends the edgemetal turned outwardly with a backward curve from the aperture andprojecting as tongues, hooks, or barbs to grasp plaster, as herein setforth.

2. A lath of sheet metal having at intervals throughout apertures ofoblong shape, each having at its two short sides or ends projectingcurved tongues of the metal turned outward in forming the apertures,essentially as shown and described.

3. A lath of sheetinetal having at intervals throughout oblongapertures, each having at its two short sides or ends projecting curvedtongues of the metal turned outward in forining the openings, and thesaid tongued apertures arranged in diagonal lines across the sheet, asshown and described.
